BOTTLE-STOPPEH.

Specification of Letters Patent.

Patented March 12, 1907.-

Application filed April 20,1906. Serial No- 312,772.

To all whom it may concern.-.

Be it known that 1, AUGUST W. CORD ES, a citizen of the United States,'residing at the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bottle- Stoppers, of which the following is a full, clear, and exact description.

My invention relates to bottle-stoppers of that class in which the "cap is removable or replaceable at will upon the bottle and in w 'ch cam means are employed for making a good sealing engagement when the parts are in closed relation.

,A bottle-cap of this description forms the subject-of my prior application, Serial No. 291 ,546, filed December 13, 1905. The pres ent case relates to an improvement of this type of cap or stopper in which the parts are made more efficient, more durable, and more practical for the 'oses of manufacture.

With these an ot er objects in view my invention consists in the construction, com-.

bination, in the location, and in the arrangement ofparts, as hereinafter set forth and shown and finally particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a complete cap embodying the princi les of my invention applied to a bottle. Flg. 2 is a side view of the same, partly in section. Fig. 3 is a detail view showing the construction of part ofthe ca Fi 4 is a pers eetive view showing a ormo bottle whic is advantageously employed in my invention. Fig, 5 1s a side view, iplartly in section, showing a slightly-modi ed form of clampin -ring. Fig. 6 is a detail view of one of the rfepending fingers. .Fi 7 is a sectional view showing the cap 0% Fig. 5 in its open or disengaged relation, and Fig. 8 shows a sli htlymodified bottle.

T e essential principle which I employ in the present and in my above-mentioned application depends upon the inward deflection of fingers having cam-surfaces which engage the under side of a bead upon the bottle neck. This I accomplish by a clamping-ring which is moved or cammed downward to engage exterior cam-surfaces upon the dependm fingers.

in order that the depending fingers properly perform their functions, 1t is necessary that the be specially formed, and the particular s ape and construction of these fingers constitutes the important part of the present invention. It is also necessary, that the clampmg-ring be dproperly constructed and properly organize with relation to the fingers in order to secure the best results.-

This is partly by reason of the fact thatthe cap is entirely made of sheet metal which is not very strong or very rigid unless it is reinforced and acted on in the proper way. The parts are also made in a die-press, which does not ive a perfect finish to the sheared edges of t e metal parts. This must, there fore, be taken account of in order that the action may be uniform and perfect for all caps in spite of the imperfections of 'dieress work and the inherent weakness of thins eetmetal stampings.

Referring tothe drawings, in which'like parts are designated by the same reference-- sign, 1 indicates a bottle of ordinary or any preferred construction, and 2' denotes a cap constructed in accordance with the principles above outlined. The cap is formed w1th a disk or plate 3, the edges of which are flanged or drawn downward, so as to produce a rim 4. Atspaced points upon the periphcry of the rim are arranged the depending fingers 5, of which three are shown, but which may be of any desired number. 6 designates the usual sealing-disk, of cork or any suitable packing material, which is contained within the cap and held in place by the rim 4. These features are of the same construction as in my prior application above mentione and form no part of the invention of-the present case.

The lower extremities of' the de ending fingers 5 are embossed or ribbed for t e dou rigi ty thereto-and to roduce cam-surfaces with smooth rounded aces upon which the 'lower part 7 'considerab y enlarged over the supporting-stem 8 and is indented both inward and outward at such enlarged extremity by alternating corrugations or ribs; The outwardly -point1ng corrugations are indi-' cated at 9 and 10, while the inwardlyointing corrugations are shown at 11. hese corrugations are conveniently made curved, rather than straight, in the direction of their length, by which absolute stiffness and rigidity is made possible. In addition to the ble piurpose of imparting-great strength and ger which I preferis illustrate parthereto.

formed upon its upper edge andwhich.

-3o work' against lugs 16, embossed upon the rigidity thus secured the'corrugations form cam-surfaces,.as clearly shown in Figs. 2, 5,

land 7. The outwardly-pointingribs or corrugations 9 and 10 form exterior cam-surfaces for the clamping-ring, while the-interi'or-pointing ribs or corrgations 11 produce a cam-surface for engagement with the under side ofthe usual bead upon a bottleneck. The exterior and interior cam-surfaces are respectively designated as 12. and '13 in the drawing. I 3

From anfinspection of Figs. 2, 5, and 7 it will be seen that the inner cam-surface, which bears against the shoulder on the botle,vis located directly opposite the reversed exterior surface, upon which the" ring acts; the 'two converging cams thus forming a wedge between the ring and the bottle. Thus when the ring is foreednaxiallydownward the leverage ofa wedge is obtained to draw the cap against the mouth of the bottlef This construction adds greatly to the efliciency of vthestop er The c amping-ring is preferably from sheet metal and beaded-or. ribbe ,in such a'wa .nthe drawings I have shown a clamping-ring 14 with spiralfwedge surfaces rim '4. I make the number" oflugs 16 ex actly correspondingto the numb'er of'depending fingers 5 and arrange the lugsin vertical alinement'over the fingers as shown. in Fig. 3. This arrangement has an important practical advantage, which will hereafter a'p ear, although, of course, it is not absolute y essential. v In Figs: 1- and 2 the clamping-ring is I beaded at 17 andhas a lower lip or edge 18,

somewhat inclined, and forming an engaging shoulder to workagainst the exterior camsurfaces 12. In Figs. 5 and 7 the lower part of the clam ing-ri'ng' is flared outward at 19, so as to su ciently'stijflen the construction,

and the inside surface of the flared portion constitutes the shoulder for engaging the exterior cam-surfaces. 1

The interior camsurfaces:13 make a fairly steep angle with the length of the fingers, so

as to give an eflicient action in drawing the cap downward upon the bottle."wh en said fingers arecammed inward.

' The operation is. as follows; The cap is placed uponthe bottle with the clasp 5mg ring 14 turned'to' the left: as far'as it 1 go,

. in which relation'it isarrested by the engagement ofthe lugs 16 withthe vertical surfaces '20. of the In this condition the ring occ'u ies its upper position, and the'depending gers 5 are allowed totspread out by theirown resiliency,-asshown inlii .7. The cap being'app-lied-ito' a 'bot tle,'.-it is merely necessary to grasp the clamping-ring 14,.

which-is conveniently knurled or milled for this purpose, and] rotate right-handedly, I

stamgied' as to give thefproper rigidity so that the cam-surfaces 15 are borne down ward by their'engagement with the lugs 16. By this means a considerable pressure is transmitted from the lugs 16 in a downward direction through the clamping-ring, and the pressure is transmitted from the ring to the depending fingers 5. Inasmuch as the fingers are directly beneath the lugs, itis apparent that the transmission of force is m a direct line without producing any bending or breaking strains in the ring, as would be the case if the lugs were not in vertical alinement with the'fingers. The relation is indicated in Fig. 3, in which the dot-and-dashlines indicate dia rammatically the manner of operation of the clamping-ringf It will be apparent that the clamping-ring acts exactly like a simple wedge. As the clamping ring moves downward the lip 18 or the inside surface of the flared portion 19 bears against the exterior cam-surfaces 12 of the fingers, which are thereby forced .inward.

.In this action the internal cam-surfaces 13 of the fingers bear against the under side of the usual bead on a bottle and 'draw the cap downward into sealing relation,-which movement is efliciently accomplished by the wedge-like action of the fingers. In some cases I employ a single central corrugation or rib 13, Fig. 6, in place of the double corrugations 11. (Shown in Fig. 3.) This is a simpler construction; but I prefer the double ribs. in practice, since they impart greater strength and rigidity to the fingers and also because they give an eflicient'friction-s'urface 'to enga e the .bottle neck, for a purpose which will'presently appear.

=A very important feature of my invention relates to the way in which the cap is prevented from rotating on the bottle by the turning movement imparted to the device when the ring is rotated. .In previous stopers this has been a serious difficulty and lias led to much inconvenience, 'it having been necessary to hold the cap fast by some means while the ring was being turned.

With my device while an ordinary bottle at the initial stages of the clamping action.

In Fig. 8 the usual bead has one or more ribs 22 thereon," cast or formed at the time the bottle is manufactured. With this. conigs struction it is evident that-the verticalshouh der oithe rim at each side-of finger will en- 3o ing depending fingers, a bottle having a bead gage with the rib on the bottle-neck and I prevent the cap from rotating.

What I claim is 1. A bottle-stopper comprising a cap or disk having depending fingers corrugated.

with exterior and lnterior cam-surfaces curved in the direction of their length, whereb the fingers are made absolutely stiff or rigi and a clamping-ring sup orted to bear against said exterior cam-su aces.

, 2. Incombination with a bottle having'a beaded neck roughened or notched upon its under surface, a cap having depending fingers with internal corrugations to engage 's'ald roughened or notched portion of the bottle. 3. In combination with a bottle having a neck with a bead roughened or notched upon its under side, a cap or disk having depend.

ing fin ers arranged to bear against said notche or roughened surface, and a relatively revoluble part arranged to move said fingers inward.

4. In combination with a bottle having a neck with a bead, the under. surface of which is roughened or notched, a cap or stopper hav-s ing fingers to engage said roughened surface,

and a part to tighten said fingers when said part is rotated, t e fingers being'held against rotation by said roughened surface.

5. In combination with a bottle-cap havwith means to prevent independent rotation of the cap thereon.

6. A bottle-stopper, for use in connection with a bottle having a shoulder on the neck thereof, the same comprising a disk having depending fingers provided with inner and outer cam-surfaces set at an angle .to each stopper is applied to a bottle,

other and to the plane of the body of said. fingers, and a verticall -movable ring embracing said fingers an adapted, when theto act upon the posite each other to form a wedge, an axially: 1

movable ri'ng embracing said fin ers and bottle, to act upon the surface of each wedge and force the interior surface thereof into engagement with the shoulder on said bottle,

or drawing the cap downwardly thereon,

and cooperating means on the cap and the ,ring for forcing the latter axially when it is rotated.

. 8. A bottle-stoppercomprising a cap and a ring surrounding the cap and rotatable with respect thereto, in combination with a bottle and cooperating devices on the bottle and cap to prevent the latter from rotating when the ring is turned.

In Witness whereof I subscribe my signature in the presence of two witnesses.
